1.With self-adjustment ability
X-shaped(45°-45°) of curved groove on cross section design makes it self-aligning. Even small misalignment exists on the mounting surface,this design can help absorb it and maintain high precision, smooth and stable linear motion.
2. High rigidity, equal load on four direction design
The 45-degree contact angle design of the four rows of steel balls and the raceway allow the steel balls to achieve the ideal two-point contact,and can withstand the action and reaction force from the radial and lateral direction.Meanwhile,preload can be applied to increase extra rigidity if necessary.
3.Interchangeable
Because of the strict control on manufacturing process,the dimensional accuracy is stable and within the set tolerance.Besides the ball retainer design can prevent steel balls from falling out.Therefore when assembling,blocks are interchangeable within the same spec and still maintain consistency of preload and accuracy.

2. Low profile, High rigidity, equal load on four direction design
The 45-degree contact angle design of the four rows of steel balls and the raceway allow the steel balls to achieve the ideal two-point contact, and can withstand the action and reaction force from the radial and lateral direction. Meanwhile, preload can be applied to increase extra rigidity if necessary.Reduce the combined height of the slide block and the slide rail, shorten the length of the slide block, to achieve miniaturization.

Crossed Roller provides high rigidity and high accuracy linear movement with non-recirculating rollers design.By cross-arrangement of rollers,it will hugely reduce friction meanwhile provide high rigidity for rollers to bear heavy loads. Crossed roller is mainly used in high precision machine and measurement equipment such as circuit board printer,optical measurement instrument,X-ray equipment or base for multiple kinds of instruments.
